FOREWORD
This repair manual has been prepared to provide essential
information on body panel repair methods (including cutting
and welding operations, but excluding painting) for the
TOYOTA RAV4 5-DOOR.
Applicable models: SXA11 series
This manual consists of body repair methods, exploded diaœ
grams and illustrations of the body components and other
information relating to body panel replacement such as hanœ
dling precautions, etc. However, it should be noted that the
front fenders of the TOYOTA model is bolted on and require
no welding.
When repairing, don't cut and join areas that are not shown in
this manual. Only work on the specified contents to maintain
body strength.
Body construction will sometimes differ depending on specifiœ
cations and country of destination. Therefore, please keep in
mind that the information contained herein is based on veœ
hicles for general destinations.
For the repair procedures and specifications other than colliœ
sion-damaged body components of the TOYOTA RAV 4
5-DOOR refer to the following repair manuals.
If you require the above manuals, please contact your TOœ
YOTA Dealer.
All information contained in this manual is the most up-to-
date at the time of publication. However, specifications and
procedures are subject to change without prior notice.

DTC P0325 Knock Sensor 1 Circuit Malfunction
CIRCUIT DESCRIPTION
A knock sensor is fitted to the cylinder block to detect engine knocking. This sensor contains a piezoelectric
element which generates a voltage when it becomes deformed, which occurs when the cylinder block vi-
brates due to knocking. If engine knocking occurs, ignition timing is retarded to suppress it.

If the ECM detects the above diagnosis conditions, it operates the fail safe function in which the corrective
retard angle value is set to the maximum value.

CIRCUIT DESCRIPTION
The shift solenoid valve SL is turned ON and OFF by signals from the ECM to control the hydraulic pressure
acting on the lock−up relay valve, which then controls operation of the lock−up clutch.

DTC 12 Actuator Magnetic Clutch Circuit
CIRCUIT DESCRIPTION
This circuit turns on the magnetic clutch inside the actuator during cruise control operation according to the
signal from the ECU. If a malfunction occurs in the actuator or vehicle speed sensor, etc. during cruise con-
trol, the rotor shaft between the motor and control plate is released.
When the brake pedal is depressed, the stop light switch turns on, supplying electrical power to the stop light.
Power supply to the magnetic clutch is mechanically cut and the magnetic clutch is turned OFF.
When driving downhill, if the vehicle speed exceeds the set speed by 15 km/h (9 mph), the ECU turns the
magnetic clutch OFF. If the vehicle speed later drops to within 10 km/h (6 mph) above the set speed, then
cruise control at the set speed is resumed.

Stop Light Switch Circuit
CIRCUIT DESCRIPTION
When the brake is on, battery positive voltage normally applies through the stop fuse and stop light switch
to terminal STP− of the ECU, and the ECU turns the cruise control off.
A fail−safe function is provided so that cancel functions normally, even if there is a malfunction in the stop
light signal circuit.
If the harness connected to terminal STP− has an open, terminal STP− will have battery positive voltage and
the cruise control will be turned off, also SET not occurring.
Also, when the brake is on, the magnetic clutch is cut electrically by the stop light switch, turning the cruise
control off. (See page DI−338 for operation of the magnetic clutch)

HOW TO USE THIS MANUAL B
This manual provides information on the electrical circuits installed on vehicles by
dividing them into a circuit for each system.
The actual wiring of each system circuit is shown from the point where the power
source is received from the battery as far as each ground point. (All circuit diagrams
are shown with the switches in the OFF position.)
When troubleshooting any problem, first understand the operation of the circuit where
the problem was detected (see System Circuit section), the power source supplying
power to that circuit (see Power Source section), and the ground points (see Ground
Points section). See the System Outline to understand the circuit operation.
When the circuit operation is understood, begin troubleshooting of the problem circuit
to isolate the cause. Use Relay Location and Electrical Wiring Routing sections to find
each part, junction block and wiring harness connectors, wiring harness and wiring
harness connectors, splice points, and ground points of each system circuit. Internal
wiring for each junction block is also provided for better understanding of connection
within a junction block.
Wiring related to each system is indicated in each system circuit by arrows (from

, t o ). When overall connections are required, see the Overall Electrical Wiring
Diagram at the end of this manual.
